HP Designjet L25500 Printer Series - Maintenance and troubleshooting guide (second edition)

If the problem remains after removing the substrate jam, unload the take-up reel from the front panel and
load it again.
Take-up reel does not wind
Predictably, if the take-up reel is not winding as anticipated, the printed output is likely to end up on the
floor. If the printer recognizes a problem with the take-up reel, it interrupts the print job until the issue is
corrected. If the printer does not recognize a problem, the job continues to print. The following table
highlights possible issues and solutions.
